When codec's ASRC was enabled, the DA and AD filters use
the reference clk which tracks the I2S clks.
And if the I2S clks' timing of open and close are not expected,
this patch allows the filters to switch to use sysclk if
ASRC's ref clks disappeared and could fix the below possible issues:
1. Avoid DA filter to keep surplus samples.
2. Avoid that AD filter works failed during dapm's power on.
For example,
if I2S clks were closed before dacdat during playback off
due to jack unplug, it causes ref clks disappeared and
DA filter remained some samples which will produce pop noise
on the next HP playback.
ASRC auto-disable could clear the samples during the playback off.

platforms->of_node and codes->of_node are assigned in probe function,
and of_node_put is called at the end of probe function, because of_node
seems to be not used after probe functon
In this patch, of_node_put is moved to platform remove function in case
of_node is used at any occasions after probe function in the future.

Because Rui is now going to focus on work that is not related to the
maintenance of the thermal subsystem in the kernel, Rafael will start
to help Daniel with handling the development process as a new member
of the thermal maintainers team. Rui will continue to review patches
in that area.
The thermal development process flow will change so that the material
from the thermal git tree will be merged into the thermal branch of
the linux-pm.git tree before going into the mainline.
Update the information in MAINTAINERS accordingly.

While sanitizing the hardware state we're currently forcing
the pipe bottom color legacy csc/gamma bits on. That is not a
good idea as BIOSen are likely to leave gabage in the LUTs and
so doing this causes ugly visual glitches if and when the
planes covering the background get disabled. This was exactly
the case on this Dell Precision 5560 tgl laptop.
On icl+ we don't normally even use these legacy bits
anymore and instead use their GAMMA_MODE counterparts.
On earlier platforms the bits are used, but we still
shouldn't force them on without knowing what's in the LUT.
So two options, get rid of the whole thing, or do what
intel_color_commit() does to make sure the bottom color state
matches whatever out hardware readout produced. I chose the
latter since it'll match what happens on older platforms when
the primary plane gets turned off. In fact let's just call
intel_color_commit(). It'll also do some CSC programming but
since we don't have readout for that it'll actually just set
to all zeros. So in the unlikely case of CSC actually being
enabld by the BIOS we'll end up with all black until the first
atomic commit happens.
Still not totally sure what we should do about color management
features here in general. Probably the safest thing would be to
force everything off exactly at the same time when we disable
the primary plane as there is no guarantees that whatever the
LUTs/CSCs contain make any sense whatsoever without the
specific pixel data in the BIOS fb. And if we preserve the
primary plane then we should disable the color management
features exactly when the primary plane fb contents first
changes since the new content assumes more or less no
transformations. But of course synchronizing front buffer
rendering with anything else is a bit hard...

If sd_max is unsigned, then sd_max - GSS_SEQ_WIN is a very large number
whenever sd_max is less than GSS_SEQ_WIN, and the comparison:
seq_num <= sd->sd_max - GSS_SEQ_WIN
in gss_check_seq_num is pretty much always true, even when that's
clearly not what was intended.
This was causing pynfs to hang when using krb5, because pynfs uses zero
as the initial gss sequence number. That's perfectly legal, but this
logic error causes knfsd to drop the rpc in that case. Out-of-order
sequence IDs in the first GSS_SEQ_WIN (128) calls will also cause this.

This patch adds a set of tests of BPF_LDX_MEM where both operand registers
are the same register. Mainly testing 32-bit JITs that may load a 64-bit
value in two 32-bit loads, and must not overwrite the address register.

This patch adds a tests of ALU32 and ALU64 LSH/RSH/ARSH operations for the
case when the two operands are the same register. Mainly intended to test
JITs that implement ALU64 shifts with 32-bit CPU instructions.
Also renamed related helper functions for consistency with the new tests.

This patch replaces the current register combination test with new
exhaustive tests. Before, only a subset of register combinations was
tested for ALU64 DIV. Now, all combinatons of operand registers are
tested, including the case when they are the same, and for all ALU32
and ALU64 operations.

This patch expands the register-clobbering-during-function-call tests
to cover more all ALU32/64 MUL, DIV and MOD operations and all ATOMIC
operations. In short, if a JIT implements a complex operation with
a call to an external function, it must make sure to save and restore
all its caller-saved registers that may be clobbered by the call.

This patch adds tests to check that the source register is preserved when
zero-extending a 32-bit value. In particular, it checks that the source
operand is not zero-extended in-place.

This patch adds a series of test to verify the operation of BPF_ATOMIC
with BPF_DW and BPF_W sizes, for all power-of-two magnitudes of the
register value operand.
Also fixes a confusing typo in the comment for a related test.

This patch updates the existing tests of BPF_ATOMIC operations to verify
that a 32-bit register operand is properly zero-extended. In particular,
it checks the operation on archs that require 32-bit operands to be
properly zero-/sign-extended or the result is undefined, e.g. MIPS64.

This patch adds a series of tests to verify the behavior of BPF_LDX and
BPF_STX with BPF_B//W sizes in isolation. In particular, it checks that
BPF_LDX zero-extendeds the result, and that BPF_STX does not overwrite
adjacent bytes in memory.
BPF_ST and operations on BPF_DW size are deemed to be sufficiently
tested by existing tests.

The error returns for various cases detected by get_prefetchable_mr() get
confused as it flows back to userspace. Properly label each error path and
flow the error code properly back to the system call.
